•Patients are eligible if they are undergoing non cardiac surgery; age > 45 years, have an expected length of hospital stay > 24 hours for surgical reasons, AND fulfill any one of the following six criteria: history of coronary artery disease, peripheral vascular disease, history of stroke thought due to atherothrombotic disease, hospitalization for congestive heart failure within 3 years of randomization, undergoing major vascular surgery OR fulfill any 3 of the following 7 risk factors: undergoing high-risk type surgery (intrathoracic, intraperitoneal), any history of congestive heart failure, diabetes and currently on an oral hypoglycemic agent or insulin therapy, pre-operative serum creatinine > 175 µmol/L (>2.0 mg/dl), age > 70 years, history of transient ischemic attack, undergoing emergency/urgent surgery
•Are the trial subjects under 18? no
•Number of subjects for this age range:
•F.1.2 Adults (18-64 years) yes
•F.1.2.1 Number of subjects for this age range
•F.1.3 Elderly (>=65 years) yes
•F.1.3.1 Number of subjects for this age range

•Contraindication to metoprolol including any of the following: significant bradycardia (heart rate < 50 beats per minute); second or third degree heart block without a pacemaker; asthma that has been active within the last decade (i.e. a clinical diagnosis of asthma and use of regular inhaled steroids, or beta agonists at least once per week over the period of a month, any time in the last ten years); and a history of COPD with bronchospasm on pulmonary function tests (i.e. an increase in FEV1 > 12% and of at least 200 ml, 15 minutes after inhalation of a beta 2 – agonist).
•Clinical plan to use a beta-blocker preoperatively or during the first 30 postoperative days
•Prior adverse reaction to a beta-blocker
•CABG surgery with complete revascularization in the preceding 5 years and no evidence of cardiac ischemia since the CABG surgery
•Patients undergoing low risk surgical procedures (e.g. transurethral procedures [transurethral prostatectomies (TURPs), stone baskets, etc], ophthalmologic procedures under topical or regional anesthesia [cornea transplants, cataract surgery, etc], and surgeries with limited physiological stresses [digital re-implantation, nerve repairs, etc] )
•Concurrent use of verapamil; OR
•Prior enrollment in this trial
